Children with autism may struggle with sensory issues that lead to sensory seeking or sensory avoiding behavior. We explore these two types of behavior, their causes, the problems they may create and how they can both lead to sensory overload.

Sensory Seeking vs Sensory Avoiding in Autistic Children

Many autistic children have a variety of sensory processing issues that can affect their behavior, of which the main two types are sensory seeking and sensory avoiding. Join us as we explore the difference between these two categories of sensory processing issues in autistic kids and how you can help them understand their sensory experience better.

Understanding autistic children who are sensory seeking

If your child prefers to get a lot of stimulation from their environment, they are likely sensory seeking. Autistic children who are sensory seeking are considered “hypo-responsive” and tend to exhibit the following sensory seeking symptoms or characteristics:

• Prefers to be moving
• Likes to smell things
• Enjoys being touched, tickled or massaged
• Has a habit of fidgeting with things
• Standing very close to people when talking to them
• Likes to jump, hop, spin, rock and other repetitive motions
• Will slam or thrust their body into things
• Enjoys touching objects and people
• Likes loud noises and enjoys making them
• Likes to put non-food items in their mouth and chew on things
• Enjoys engaging in risky behavior
• Prefers to go barefoot

What causes sensory seeking behavior?

As with autism, exactly what causes sensory seeking behavior is not yet known. We only know that some autistic children are under-responsive to sensory input, others are hyper-responsive and yet others are a mix of the two. Because of how their bodies experience and process sensory input, they will then engage in behavior that will help them meet their sensory needs.

The problems affecting those who are sensory seeking

If you have a sensory seeking child, it may have a negative impact on their life, especially if they do not learn how to manage their sensory needs in appropriate ways. Here are three examples of how a child may struggle if they are sensory seeking.

Might cause themselves physical harm

Firstly, a child may unknowingly engage in dangerous behavior to meet their sensory needs. For example, they may jump from dangerous heights or come up with their own risky stunts to stimulate themselves. 

Might be ostracized by others

Secondly, certain behaviors might provoke negative reactions from those around them. For example, if an autistic child randomly touches other children and adults without their consent, these people may choose to avoid the child.

Might struggle in learning spaces

Finally, they may struggle to pay attention due to the fact that they are constantly seeking out higher levels of stimulation. This could negatively impact learning and academic performance in a learning environment.

How to help those who are sensory seeking

Your first port of call when it comes to helping an autistic child who is sensory seeking is a professional, such as an occupational therapist, who will be able to directly assist your child with their sensory seeking behavior. 

There are also activities that you can engage in at home to help your child meet and manage their sensory needs. Some examples of these activities include:

• Jumping on a trampoline
• Bouncing on an exercise ball
• Climbing on a jungle gym
• Have a pillow fight
• Using a weighted vest
• Letting them play with specifically designed sensory toys, such as weighted toys, scented play-doh and sensory bins
• Practicing respecting personal boundaries
• Practicing asking and waiting for explicit consent before touching anyone

Understanding autistic children who are sensory avoiding

If your child prefers to avoid being stimulated by their environment, they are likely sensory avoiding. Autistic children who are sensory avoiding are considered “hyper-responsive” and tend to exhibit the following:

• Has a greater sensitivity for smells
• Easily startled by unexpected sounds or bright lights
• Avoids crowded areas in favor of quieter environments
• Filters out fewer sounds compared to neurotypical children, which means they “hear more”
• Likes to wear headphones or earplugs to block out unwanted sounds
• Incredibly sensitive to pain
• Doesn’t like clothes with certain textures or clothes that are too tight
• Finds seams or tags in clothes incredibly annoying
• Is very picky about what they like to eat
• Doesn’t like being touched, even if it’s affectionately or playfully
• Dislikes being barefoot

What causes sensory avoiding behavior?

As with autism, we don’t know what causes sensory avoiding behaviors. What we do know is that some autistic children are overstimulated by certain activities or situations, which they then try to avoid so as not to overwhelm themselves.

The problems affecting those who are sensory avoiding

Sensory avoiding behaviors can affect your child negatively, most especially if they do not learn healthy coping mechanisms to meet their sensory needs. Here are a few ways sensory avoiding behavior can impact your child’s life.

May avoid activities and environments to their detriment

A sensory avoidant child may develop anxiety around activities and environments that make them uncomfortable, even if these things would benefit them, such as playing games with their peers or exercising on a playground.

May struggle to make social connections

Connected to the point above, if an activity or space is uncomfortable for your child with autism, they are likely to avoid it, which could, in turn, cause them to withdraw from social situations. For example, if they don’t take part in school games during breaks or are anxious about attending birthday parties, they may struggle to make social connections with other children.

Another example is that while other children may enjoy playing on a bouncing castle and all the rough and tumble that comes with it, a sensory avoidant child may not. Consequently, they may have to deal with feelings of loneliness, frustration, anger, sadness or being “left out” when they are the odd person out in such situations.

How to help those who are sensory avoiding

Again, as with sensory seeking children, you should seek out specialists who can help your sensory avoidant child learn to manage their sensory challenges. An occupational therapist or other health professionals can help you address your child’s needs.

There are also various precautions you can take to help your sensory avoiding child not feel overwhelmed. Some examples of these include:

• Decluttering an environment
• Keeping a pair of noise-canceling headphones nearby
• Making sure their clothes are not too snug and are made from materials that they are comfortable wearing
• Trimming the labels off their clothes
• Considering a weighted vest or blanket to help them feel more comfortable when overstimulated
• Preparing a quiet, calming space for them at home so that they have an area to retreat to if needed

Autistic children can have both sensory seeking and sensory avoidant traits

While we’ve split sensory seeking and sensory avoiding into two sections, it’s important to note that some autistic children can have characteristics of both categories.

What about sensory overload?

Regardless of whether your child is sensory seeking or sensory avoidant, they can still experience sensory overload. Sensory overload is when your brain is overloaded by the sensory information it is receiving. The amount or type of sensory information that causes sensory overload differs from person to person.

Sensory overload symptoms

Here are some of the signs of sensory overload:

• Anxiety, irritability, stress, fear or panic
• Overexcitement or restlessness
• Physical discomfort
• Need to limit source of overload by covering ears or closing eyes
• Need to leave area or space where the cause of the sensory overload is
• Tantrums or “meltdowns”

How to help with sensory overload

Here are some tips for managing and coping with sensory overload:

• Take preemptive steps to avoid triggers that cause sensory overload for your child, such as asking for lights or sounds to be turned down. 
• Ensure you are able to easily leave the location so that your child has the space to recover from sensory overload. 
• Be prepared by making sure your child has enough rest the night before and is properly hydrated. 
• Have a sensory toolkit filled with items that can help your child calm down, such as noise canceling headphones, sunglasses, fidget spinners and other objects that can help your child relax. 
• Talk to a health professional about medications that might be useful in avoiding or minimizing the consequences of sensory overload. 
• If possible, make sure those around your child are aware that they might become overwhelmed by specific triggers and explain to them what those triggers are. 
• Most importantly: help your child identify and understand their own sensory needs and triggers as far as possible – this could go a long way in helping them learn to manage their sensory issues in healthy ways. 

Discover how Lighthouse Autism Centers can help your child

At Lighthouse Autism Center, we offer our unique Lighthouse Fusion® ABA therapy program which combines the best aspects of ABA and speech therapy. This program, as well as our autism resources, are vital in helping your child unlock their full potential.

The picture exchange communication system, or PECS, is a teaching system that can help an autistic child or another individual with speech difficulties improve their communication skills. We take a look at PECS’ role in ABA therapy and unpack how it works.

Picture Exchange Communication System and its use in ABA Therapy

Many autistic children have difficulties communicating verbally. PECS is one of the many tools we use in ABA therapy to help them increase their independence and improve their outcomes. Join us as we further unpack PECS, how it works, the benefits it offers, and more.

What is PECS?

The picture exchange communication system, or PECS, is a communication system that was developed in the USA in 1985 by Andy Bondy, Ph.D., and Lori Frost, M.S., CCC-SLP, the founders of Pyramid Educational Consultants, Inc. It is based on the book “Verbal Behavior” by B. F. Skinner. 

This augmentative or alternative communication system was first used to assist autistic preschool students who were part of the Delaware Autism Program. It is now also used to help people of all ages with communication difficulties that are caused by many conditions. 

How PECS works

One of the downsides to other programs and methods designed to help those with communication issues, such as sign language and picture point systems, is that they rely on the teacher to initiate communication with a student. This creates a situation where the student learns to only respond in communication and to never initiate it themselves. The main goal of PECS is to help address this by teaching students to communicate more spontaneously using specific prompting and reinforcement strategies and avoiding verbal prompts, as well as improving their functional communication skills. 

Implementing PECS

Regardless of whether you are using the PECS program for autism or other causes of communication-related challenges, it has a specific process that you need to follow.

Complete reinforcer sampling

Before the PECS protocol is implemented, it’s important to first complete “reinforcer sampling.” Reinforcer sampling simply refers to the creation of an inventory of activities, toys, or other items that the student likes so that these items can be used as motivators during PECS. 

This inventory is created using an assessment process that can be completed in numerous ways, such as asking caregivers, observing the student and what they choose most and least often, and presenting the learner with pairs of options to see what they like the most. The reinforcers that are chosen will need to be consistently appealing to the learner in order to assist with PECS.

The six phases of PECS

Phase 1: How to communicate

In phase one, the student learns to initiate communication by exchanging pictures for things they really want or activities they want to take part in with a second trainer, who is the student’s communicative partner. (These desirable items and activities were identified during the complete reinforcer sampling stage.)

Phase 2: Distance and persistence

During phase two, the student learns to use this skill of exchanging a picture to get something they want in different places. They learn to do this by seeking out their communicative partner. They are also taught to initiate communication with other communicative partners using the same system. This is accomplished using different desirable items and activities. 

Phase 3: Picture discrimination

During phase three, the student is now tasked with asking for two or more of their favorite things, using multiple pictures. These images are stored in a PECS Communication Book, which allows for easy removal and return of images used by the student.

Phase 4: Sentence structure

In phase four, the student learns to complete basic sentences using what are known as Sentence Strips. These strips begin with an “I want” picture, with the student adding the picture of the item they desire to the strip from the PECS Communication Book. Once the student has demonstrated the ability to make this request, additional detail is added to these statements using descriptors, including the number, color, shape, or size of the object that they want.

Phase 5: Responsive requesting

Phase five asks the student to engage with the question “What do you want?” and to respond using the skills and tools they learned in phase four. When asked this question, the student must use the Sentence Strips and pictures from their PECS Communication Book to provide an answer.

Phase 6: Commenting

In the final phase of PECS, the student learns to answer other questions such as “What do you see?”, “What do you hear?” and “What do you smell?”. This is done by teaching them to use additional phrases such as “I see,” “I hear,” and “I smell” on their sentence strips, expanding their requests beyond “I want.”

The benefit of PECS

There are many benefits to teaching using PECS. Here are some of the advantages that it offers to autistic children:

• Helps make communication a more understandable process
• Improves the initiation of communication
• Can decrease problem or negative behaviors
• Can help improve social skills and allow students to build relationships
• Easy to learn for a student’s partner
• Increases the use of speech in some learners

Learn how assistive communication technology is used in ABA to improve social communication and behavior in autistic people.

Technology and ABA

Applied Behavior Analysis (ABA) is an indispensable tool used in the treatment of Autism Spectrum Disorder (ASD). Thus, it stands to reason that ABA therapy is inextricably linked to technological advancements that improve the quality of ABA for therapists and patients alike. 

Assistive communication devices for autism

Figuring out how to improve social communication skills in autism sits at the heart of ABA therapy. Many practitioners and patients often turn to technology for solutions. 

The development of assistive communication devices for autism has tracked the rise of technology, and these have been employed with great success in recent times. Here are some of the most innovative new developments in the technological dimension of ABA, focusing on assistive communication technologies and devices for autism. 

Augmented Reality (AR)

Studies have shown that Augmented Reality (AR) technology provides an enjoyable and stimulating environment, which reduces boredom in autistic people while increasing enjoyment and motivation. 

AR also improves social skills and communication in patients with an increased interest in the education process through participation.

In early experiments with Google Glass, the camera would interpret facial expressions of people for the patients and display a corresponding emoji. This provided therapists with a deeper understanding of the link between social situations and the behavior of autistic people. Additionally, the use of AR role-playing and interactive autism games for social skills significantly boosted the recognition of social cues. 

Virtual Reality (VR)

Although virtual reality (VR) has been around for a long time, it has only recently become more accessible and affordable. Head-mounted displays (HMDs) like Google’s Cardboard, which houses a smartphone loaded with a VR autism app, have demonstrated remarkable improvements in autistic people – especially with social functioning, emotion recognition, speech, and language. 

Video-modeling

Incorporating video into ABA is largely based on Albert Bandura’s social learning theory (1977). This simply means people learn by watching and copying each other. 

Video-modeling, according to modern parlance, is less threatening to autistic children than face-face modeling and seems to be more motivating. It also allows patients to focus on one or two skills at a time without overwhelming them. 

Mobile apps

There has been a surge in the development of applications or apps to turn our mobile devices, like tablets and phones, into assistive communication devices for autism. Here are a few apps that have successfully dealt with communication and behavioral issues in autistic patients.

Language and Cognitive Therapy for Children (MITA)

Operating System – Android and iOS

This app delivers an almost unlimited number of cognitive exercises for autistic children with speech delays. Having passed clinical studies, MITA (which stands for Mental Image Therapy for Autism) uses simple vocabulary with higher forms of language and adaptive activities specifically for early intervention. Other features include playtime rewards and offline viewing.

Symbotalk

Operating System – Android and iOS

Symbotalk helps autistic children to communicate verbally through flexible boards and sub-boards, as well as augmentative and alternative communication (AAC) systems. 

The app helps children associate symbols and pictures with audio. It also allows you to upload your own images and record your own voice to make it easier for the child. 

Proloquo2Go

Operating System – iOS

This is not a free app but has won awards for innovation in giving a voice to children who can’t speak. Autistic children who find speech and communication difficult are able to communicate complexity through a highly intuitive interface. 

Parents and therapists can configure grammar, while core words can be learned through associated movement. 

Leeloo

Operating System – Android and iOS

Based on augmentative and alternative communications (AAC) as well as picture exchange communication systems (PECS), Leeloo uses cards to match words and phrases to images. 

Once a card is selected, Leeloo reveals a list of words and phrases associated with that image, then reads out the word or phrase the child selects in up to 10 different voices. 

Otsimo

Operating System – Android and iOS

Otsimo improves both speech development and behavior in autistic children and adults. 

With over 50 games, the app supports ABA interventions through the provision of progress reports as well as the ability to personalize each game to the needs of the individual child.

ABC Autismo

Operating System – Android 

ABC Autismo focuses on enhancing learning in autistic children through the use of over 40 interactive activities that promote attention and focus. Therapists and psychologists also use it as an evaluation tool to assist in diagnosing autism and other mental disorders.

Autastico II

Operating System – Android 

Autastico II focuses on improving cognitive skills, attention, and motor coordination through activities, sound, and music. Unlike other apps that are primarily functional, Autastico II also emphasizes entertainment and fun through engaging content and striking graphics. 

Dino Tim

Operating System – Android 

Dino Tim is a fun learning app for autistic children. The app follows the storyline of Dino Tim and his family, who are kidnapped by witches. Children are then required to become heroes to rescue them from the witches by conquering over 100 puzzles and activities that boost motor skills and increase attention and concentration. 

Wearable assistive technologies (WAT)

Wearable assistive technologies (WAT) are making it possible for autistic people to re-enter classrooms and other clinical environments to learn and even venture into real-world social situations through the use of real-time feedback. 

As the technologies mature, autistic people can navigate social interaction using WAT like smartwatches with haptic responses, augmented reality headsets like Google Glass, and almost invisible hearing aids. 

Hearing aids

Modern hearing aids have become so advanced that they can assess the acoustics of a room or environment and then remove sounds that it doesn’t recognize as speech. 

Even more impressive is that some hearing aids can simulate high-definition sound for music and speech. Better still is that they can be configured and controlled using mobile devices like phones and tablets. 

Neural command

Neural command makes it possible for people to control devices simply by using their brainwaves. Not unlike common software that converts text to speech on our mobile phones, neural interfaces (although still in their infancy) are being developed to integrate with speech-generating devices that allow people with severe speech impediments to “talk” using their thoughts and specially designed headsets.

Robotics

Advances in robotics aid in teaching autistic children social skills while keeping them focused during their therapies.

A recent study using NAO, a robot created by SoftBank robotics, also showed that with appropriate software, robots can be used to assess autism in children through observing play and interaction.

Artificial Intelligence (AI) and machine learning

It has recently been established that machine learning models can help predict ABA treatment programs for children with ASD and significantly assist ABA practitioners in prioritizing resources for the management of ASD from diagnostics through to intervention. 

Lighthouse Autism Center

Lighthouse Autism Center is the Midwest’s leading autism therapy institution, with world-leading autism resources and a ground-breaking Lighthouse Fusion® ABA Therapy program that fuses the best practices of ABA and speech therapy into a one-of-a-kind clinical model that delivers better outcomes for children with autism.
